A simulation method includes: a process of performing a renormalization transformation process with respect to a granular system S that is a simulation target that includes a plurality of polymers that are respectively formed of a plurality of monomer grains that are connected to each other in one dimension, on the basis of a renormalization factor λ depending on the number of times of renormalization; and a process of calculating a position vector and a momentum vector of a monomer grain in a renormalized granular system S′ by executing molecular dynamics calculation with respect to the renormalized granular system S′.
